PORTABLE ELEVATOR AND WAGON-DUMP.

Specification of Letters Patent.

Patented J an. 16, 1917.

Application filed November 25, 1912. Serial No. 733,412.

To all whom it may concern Be it known that I, PLIN C. SoU'rHwIoK, a citizen of the United States, and resident of Sandwich, county of Dekalb, and State of Illinois, have invented certain new and useful Improvements in Portable Elevators and VVagon-Dumps, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to that class of devices used for the transfer of grain from a wagon to a crib, wherein the wagon is dumped by having its forward end raised and discharges into the receiving trough of an elevator which carries the grain upward to discharge it into the top of the bin.

In devices of this kind power is applied by a suitable motor, which may be a horse power; and the object of the invention is .to improve the mechanism by which power is transmitted to the wagon-dumping element and to the elevator and to provide improved means for controlling the application of power to these two parts of the device.

The invention is fully hereinafter described, and is illustrated in the accompanying drawings in which Figure 1 is a general view in perspective of the entire device, and including a horse power; Fig. 2 is a detail side elevation of the lower end of the elevator and a portion of the receiving trough; Fig. 3 is a sectional view on the line 33 of Fig. 2; Fig. 4 is a detail side elevation of the wagon dump; Fig. 5 is a sectional view on the line 5-5 of Fig. 4; Fig. 6 is a sectional view, on an enlarged scale, on the line 66 of Fig. 5; Figs. 7 and 8 are plan views of the clutchshifting lever device, the levers being shown in section and the parts being shown in different positions; Fig. 9 is a detail elevation similar to Fig. 2 and showing a modified form of construction; and Fig. 10 is a sectional view on the line 10l0 of Fig. 9.

The device comprises a wagon dumpin mechanismgenerally designated by the numeral 15, an elevator, generally designated by the numeral 16, and a power mechanism, here represented as a horse power, generally designated by the numeral 17.

The wagon dump may take various forms as to its details, but is here shown as comprising a pair of uprights 18, 19, united at their upper ends by a cross-bar a pair of cables 21 running over suitable sheaves (not shown) mounted in the upper portion of the frame and suitably connected to a nut 22 running on a screw-rod 23 as by means of the rods 21 The screw 23 carries a beveled gear 24 and a spur gear wheel 25. The beveled gear 24 is in constant engagement with a beveled gear 26 loose on a shaft 27. The spur gear is in constant engagement with a beveled gear 28 loose on the shaft 27, through the medium of a spur gear 29 and a beveled gear 30 mounted therewith. A double faced clutch 31 is splined upon the shaft 27, and is located between the beveled gears 26, 28, and is adapted to lock either to the shaft or to be disengaged from both. This arrangement of gears pro vides for turning the screw 23 in one direction by the gear 26 for raising the forward end of a wagon wherrthe cables 21 are attached to the hubs of its forward wheels; and for turning the screw 23 in the opposite direction and at higher speed through the gear 28, for lowering the wagon.

The shipper lever for controlling the clutch 31 is represented at 32. A pair of levers 33, 34, are mounted upon the frame of the structure and in the path of an arm 35 carried by the nut 22 for engagement, the latter, when the wagon is raised to the desired extent and the former when it is lowered to the ground. These levers are connected by means of links 36 and 37 with a bell-crank lever 38, pivoted at 39 upon the frame and passing through the shipper lever 32, whereby the clutch is automatically released from engagement with either the beveled gear 26 or the beveled gear 28. This wagon dump, so far as described, is without novel features. The shipper lever 32 is manually controlled through the medium of a link rod 40 attached thereto at 41.

The elevator is usually mounted upon a truck 42, as shown, and comprises an elevating trough 43, the pitch of which may be controlled by a suitable Windlass 44 cooperating with an upright frame 45; a suitable endless lifting device 46 running in the trough, and a receiving trough 47 into which the wagon dumps and which is provided with suitable conveying mechanism for transferring the grain to the boot of the elevator spout 43. Such structures are in common use and do not require more detailed description.

One of the novel features of the improved elevator and wagon dump is the power shaft 27 extending from or driven by the motor through or past the elevator, with the conveyer mechanism withwhich it is connected to the wagon dump, where, as already described, it carries the beveled gears 26 or 28, or other suitable gears, for effecting the m ment- Of e Wag n- In the preferred form of construction as illustrated in Figs. 3 and 4, the shaft 27 carries the sprocket wheels e8, 4L9, which directly actuate the conveying belt of the elevator. These sprocket wheels are respectively carried by sleeves 50, 51, loosely mounted upon the shaft 27, the innerends of these sleeves being interlocked, as represented at 52. The hubs 53, 54, of these sleeves are journaled in boxes 55, 56, mountedin the side walls of the elevator spout 43.

With the hub 53 there is interlocked the hub of a sprocket wheel 57, loosely mounted on the shaft 27 and held in engagement with the hub 53 by means of a collar 58 secured to the shaft. A sprocket chain 59 runs on the wheel 57 and a wheel 60 for driving the conveyer belt of the receiving trough a7.

The outer end of the hub 54- is provided with a clutching face 61, coiiperating with a clutch 62 sp'lined upon the shaft 27 and controlled by a hand lever 63, whereby the elevator may be thrown into or out of action.

The linkrod 40 for manually controlling the shipper lever 32 is connected with a hand lever 64 fulcrumed upon a bracket 65 attached to one of the sides of the elevator trough 43. This bracket forms a part of a casing 66 having slots 67, 68, within which the levers 63, 64, respectively oscillate. Upon the casing 66 there is mounted an oscillating plate 69, having a laterally projecting shoulder crossing the slot 67 in the path of the lever 63, and a cam lug 71 also adapted to swing across the same slot when the plate is moved by the engagement of the lever with the shoulder 70, and by means of which the plate is swung in the opposite direction by the reverse movement of the lever.

hen the plate is swung on its pivot by the action of the lever .63 on the lug 71, its opposite edge crosses the slot 68; and when swung by the engagement of the lever 63 with the shoulder 70 this edge is drawn away from the slot 68 to permit the free movement of the lever 64. The edge of the plate 69 which coiiperates with the slot 68 is provided with a notch 72 adapted to receive the lever 64:, and having abrupt shoulders, thereby locking the lever against movement. This notch 72 is so located that when engaged by the lever 64 the latter is in its operation of the wagon dump. When, however, the lever 64 is moved in either direc- .tion from the neutral position, thereby throwing the dumping mechanism into action, it forms a barrier against the movement of the plate 69, thus preventing the lever 63 from being thrown to bring theelevator into action-this latter movement being possible only when the lever 64: is again returned to its central position opposite the notch 72. One advantage of this interlocking relation of the clutch-controlling levers,

whereby, the simultaneous operation'of the elevator and wagon dump is prevented, is I that the power mechanism is not overtaXed. The common practice of users of devices of this character is to employ horse power for driving them. Usually the team which hauls the wagon to the dump is detached therefrom and hitched to the sweep of the power device. Unless the elevator be a very short one. the work incident to the simultaneous operation of both it and the dumping device overtaXes and strains the team.

In the operation of the device as herein shown and described, the front end of the wagon is first raised sufliciently to start the flow of grain into the receiving trough of the elevator. The clutch 31 being now thrown to the neutral position by the manipulation of the lever 6a, the elevator is started by throwing the lever 63 to the position indicated in Fig. 7, thereby also looking the lever 64 against movement. When the grain ceases to flow to the capacity of the elevator with the wagon at theinclination first given it, the lever 63 is thrown to disengage the clutch 62, thereby shifting the plate 69 and releasing the lever 64. This latter lever is again thrown to engage the clutch 31 with the gear 26, still further raising the forward end of the wagon suflicient to cause further flow of the grain, The clutch v31 being again disengaged, the elevator is once more set in motion. This alternation of action of the two parts of the device may be repeated, if necessary, until the wagon is completely discharged of its load. The elevator being again stopped, the lever 63 is thrown to engage the clutch 31 with the beveled gear 28, thereby turning the screw-rod 23 in the opposite direction and lowering the wagon.

While the device is shown in Fig. 1 as arranged with the horse power to the left and the dumping mechanism to the right of the elevator, it not infrequently happens, because of the situation of a crib and surrounding objects, that thepositions of the power and dumping device must be reversed. This change is readily made by detaching the bracket and the bracket 73 to which the lever 63 is pivoted, from the wall of the elevator trough 43 to which they are shown as secured, and bolting them to the opposite wall, and shifting the wheel 57 and collar 58 to the opposite side of the elevator. These changes are made possible by reason of the fact that the sleeves 50 and 51 are identical in construction. The shaft 27 is preferably sectional, having a coupling at each side of the elevator, and these couplings may, if desired, take the form of universal oints.

In the construction illustrated in Figs. 9 and 10, the advantages of the continuous live shaft leading directly from the motor through or past the elevator to the dumping mechanism is maintained, although in this instance the shaft 27 does not carry the sprocket wheels which drive the conveyer of the elevator but is located above the end of the elevator spout, and carries a sprocket wheel 74, connected by means of a chain 75 with a sprocket wheel 76, mounted upon a short shaft 77 carrying the sleeves 50, 51, upon which the sprocket wheels 48, 49, are mounted. The wheel 74 is provided with one member of a clutch 78, the cooperating clutch member 79 being splined upon the shaft 27 and controlled by the lever 63, as in the construction illustrated in Figs. 2 and 3.

WVhile in this modification the shaft 27 isshown as being ournaled in boxes mounted within the walls of the trough of the elevator, it is immaterial whether they be so mounted that the shaft 27 passes between the two turns of the endless conveyer of the elevator or is entirely outside of this conveyer.

While the means for preventing the simultaneous engagement of the two clutches is shown as being associated with and actuated by the controlling levers, I do not desire to be limited to this detail of construction.

I claim as my invention- 1. In a portable elevator and wagon dump, in combination, a suitable motor, an elevator, and a wagon dumping device, a power shaft leading from the motor, independent means for connecting the shaft with the mechanism of the elevator and with the mechanism of the dumping device, and looking means for preventing the simultaneous engagement of the connecting means.
